Sect ion o f so l ids(Regular solids, prisms)

1. A cube of side 25mm rests on the HP on one of its faces with a vertical faceinclined at 35 to the VP. A plane perpendicular to the HP and parallel to the

VP cuts the cube 10mm away from the axis and further away from the VP.

Draw the top and sectional front views.

2. A cube of side 25mm rests on the HP on one of its faces with a vertical faceinclined at 35 to the VP. It is cut by a plane perpendicular to the VP and

inclined at 35 to the HP and meeting the axis at 20mm above the HP. Draw

the front view and sectional top view and the true shape of the section.

3. A hexagonal prism of base side 30mm and axis length 70mm rests on the HPon one of its rectangular faces with its axis perpendicular to the VP. It is cut

by a plane inclined at 30 to the VP. The cutting plane meets the axis at a

distance of 30mm from one end. Draw the top and sectional elevation and

true shape of the section.

4. A pentagonal prism of base side 40mm and length 80mm lies on the HP onone of its regular faces with its axis inclined at 45 to the VP. It is cut by a

plane parallel to VP that meets the axis the axis at 16mm from one end.

Draw the top view and sectional elevation of the prism.

5. A square prism, of side of base 40mm and axis 60mm long, rests its base onH.P. such that one of its rectangular faces is inclined at 30 to V.P. A sectional

plane perpendicular to H.P. and inclined at 60 to V.P. passes through the

prism such that a rectangular face which is making 60 with V.P. is cut into

two halves.

Sect ion o f so l ids(Cones, Pyramid, Cylinders)

1. A square pyramid of base side 20mm and the altitude 40mm rests on the HPon its base with base edges equally inclined to the VP. It is cut by a plane

perpendicular to the VP and inclined at 30 to the HP meeting the axis at

21mm above the HP. Draw the sectional plan and the true shape of the

section.

2. A hexagonal pyramid of base side 20mm and axis 55mm rests on the HP onits base with two edges parallel to the VP. It is cut by a vertical plane

inclined at 30 to the VP and cutting the pyramid at 5mm from the plan of

the axis. Draw the top view, sectional front view and an auxiliary elevation

parallel to the cutting plane.

3. A tetrahedron of edge 60mm rests on the HP on one of its faces such that onone of the edges of the resting face is perpendicular to the VP. It is cut by a

plane perpendicular to the VP and inclined to the HP in such a way that the

true shape of the section is an isosceles triangle of base 40mm and altitude

30mm. Find the inclination of the cutting plane with the HP. Also draw the

front view, sectional top view and true shape of the section.

4. A cylinder of diameter 40mm and height 50mm rests on its base on the HP.It is cut by a plane perpendicular to the VP and inclined at 50 to the HP. The

cutting plane meets the axis at a distance of 15mm from the top. Draw the

front view, sectional plan and the true shape of the section.

5. A cone of base diameter 40mm and altitude 55mm rests on its base on theHP. It is cut by a vertical plane parallel to the VP at a distance of 6mm from

the axis. The axis is nearer to the VP than the cutting plane. Draw the top

view and sectional front view.
